When I click at a tab, the correct page will be shown.
When I click at lets say the home tab, the home panel will be shown. When I click within this panel at a button to show another panel within the same tab (home), the tabpanel disappears.
How can I resolve this?

I see multple panels when I click at a tab. (see picture below)Wrong ST2.PNG
I clicked at Home tab and I see the panels: "home" and "homeover".
This isn't what I want.

Short explanation:
Tabpanel "Main" has 3 tabs which refer to the panels "home", "person", "todo".
When I click within the home panel at the button "over", the "homeover" panel should open in the same tab, which is "home".
